Abstract

Pseudocyclic arylbenziodoxaboroles are unique aryne precursors under neutral aqueous conditions that selectively react with tertiary organic phosphines or amines at room temperature to form the corresponding aryl-substituted quaternary phosphonium or ammonium salts in high yields. This reaction has been further extended to the preparation of tetraarylarsonium and tetraarylstibonium salts.
